Preparation

Basic Characteristics:

SPA7 is a powerful remote control and monitoring device. It enables to monitor logical and analog inputs status and to control outputs via GSM network. SPA7 can use SMS messages, data connection or GPRS connection (version SPA7-GPRS). The behavior of a device and names of inputs and outputs are in SMS version fully selectable via USB cable or remotely (data connection) using supplied configuration software. The defined emergency conditions may result in sending a SMS message to the list of telephone numbers (boiler failure, gas leakage, rapid drop or rise of temperature or level) including information about the failure and restoration of power supply (SPA7-BOX). The user can select analog inputs as voltage (0 to 10 V), current (0 to 20 mA) temperature (for KTY81-210 and Ni5000 sensors) or for function like another logical input. The analog inputs values can be send in actual units and values (configurable recalculation including non linear functions).SPA7 can save all the I/O values and signal changes in an optional HISTORY module. Events in the device like changes of logical inputs, analog inputs states, etc. are logged into this memory and can be readout locally and remotely as well.

Technical Data SPA7-GPRS:

Power supply: 8 – 30 V (max. 120mA for 12V)
Logical inputs galvanically separated:8 inputs (8 - 30V / 5mA for 12V)
Logical outputs galvanically separated:4 outputs (60 V / 100 mA)
Analog inputs:2 inputs ( 12 bit converter)  jumper selectable as
a) voltage 0 – 10 V

b) current 0 - 20 mA

c) temperature, KTY81-210 sensor +/-1.5 ...+/-3°C

d) temperature, Ni5000 sensor +/-0.2 ...+/-0.5°C

e) another galv. separated logical input 8 ... 30V

Port: USB 1.0, 2.0
Operating temperature: -20 to +55 °C

Advantages of SPA7-GPRS:

Simple installation - The device is delivered with a frame for mounting onto DIN rail
Easy monitoring - just send a SMS message “STATE“ to receive a message about the state of the device inputs and outputs
Configuration and Monitoring SW - user friendly PC SW works either locally via USB port or remotely using data call (or GPRS in version SPA7-GPRS)
User selectable analog inputs HW mode configuration and SW recalculation parameter and analog inputs units selection

Use of SPA7-GPRS:

Boiler houses, heating plants and heat pumps
Industrial objects – water plants, water reservoirs, small hydroelectric stations, boiler plants
Technology processes – fault report, gas leakage, drop or rise of temperature or level, freezing point monitoring
